Fasting for 48 hours would put you into keto but you would be loosing musclemass in the process of getting there so I wouldn't recommend going that route. Intermittent fasting doesn't really put you into keto unless your also cutting out carbs.

Coming from someone already thin and athletic, as long as you move a lot during your fast you’re going to lose a neglible amount of muscle/strength

Nothing noticeable at least

I have seen a guy on YouTube who made a video about studies on intermittent fasting and these study do not support your view. They showed that you loose about as much muscles mass as any other diet.

True like I said if you're not in ketosis you will lose muscle mass. If you're already in ketosis you will minimise you muscle loss. Keto is the only diet where you can actually lose fat and gain muscle at the same time.

Intermittent fasting doesn’t equal an ketogenic diet afaik

No it doesn't, but it'd often used while on keto to maximise effects of the diet.

So fasting is a bad idea in general? Cus many people practice it. I feel like it also really helped me to lose weight and go from obese to overweight.

In a very generalized broad terms - yes. May be different for individual situations.

Long term habit change is what you want to do.

I mean fasting can definitely help if your only goal is to loose weight. But if you want to put on muscle as well I wouldn't be fasting for long periods.
